Code Description

ICD-10 M87.04 is a billable code used to indicate a diagnosis of idiopathic aseptic necrosis of hand and fingers.

Key Diagnostic Point:

Idiopathic aseptic necrosis of the hand and fingers is a condition characterized by the death of bone tissue due to a lack of blood supply, specifically affecting the bones in the hand and fingers. This condition is termed 'idiopathic' because the exact cause is unknown, although it may be associated with factors such as trauma, corticosteroid use, or excessive alcohol consumption. The necrosis leads to pain, swelling, and limited mobility in the affected areas. Patients may experience joint stiffness and may have difficulty performing daily activities. Diagnosis typically involves imaging studies such as X-rays or MRI to assess bone integrity and blood flow. Treatment options may include conservative measures like rest and physical therapy, or surgical interventions such as core decompression or bone grafting in more severe cases. The condition can lead to significant orthopedic complications if not managed appropriately, including chronic pain and functional impairment.

Complexity Factors

  • Variability in clinical presentation and symptoms
  • Need for precise imaging documentation
  • Differentiation from other forms of osteonecrosis
  • Potential for co-morbid conditions affecting treatment

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify the idiopathic nature of the condition
  • Lack of imaging studies to support diagnosis
  • Misclassification with other types of osteonecrosis

Coding Guidelines

Inclusion Criteria

Use M87.04 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the diagnosis is supported by clinical documentation and imaging studies
  • The code should be used when the necrosis is confirmed to be idiopathic and not secondary to other conditions
